PRINT KEY

The PRINT key allows the operator to obtain a printout
of real-time system operating data or a printout of sys-
tem data at the “instant of the fault” on the last six faults
which occurred on the unit. An optional printer is re-
quired for the printout.

OPERATING DATA PRINTOUT

Pressing the PRINT key and then OPER DATA key al-
lows the operator to obtain a printout of current system

operating parameters. When the OPER DATA key is
pressed, a snapshot will be taken of system operating
conditions and panel programming selections. This data
will be temporarily stored in memory and transmission
of this data will begin to the printer. A sample OPER
DATA printout is shown below:

See Service And Troubleshooting sec-
tion for Printer Installation informa-
tion.
